Horns...

It's hard to critique something this beautiful but I'll try. I love the idea, composition, and style altogether. Your technique is impeccable. I think the only thing that could be different is the impact. The design definitely caught my eye, but the contrast is on the mild-side. It would be cool to see the fire pop out more, so it's convincing that it's burning. I see there are a few small bits of fire that's bright. I think there could be more of those brightness. It would also be nice to see more contrast on her skin (face). What if the bright fire reflects on her hair or face, tying the two pieces together? Another thought is that because the range of colours is limited (don't get me wrong, it's beautiful), it maybe neat if her hair was more impactful colour? That's just a thought though. I do think nearly black-and-white image with bright fire is a cool idea. I hope this helps. Overall, wow <3
